Do you guys have any experience with these on 12v nv4500 trucks? I'm wondering what the difference in spool is like between exhaust housings and which one the people with more experience recommend. After reading this entire thread about 4 times, I believe a 64.5/73 would work for me, but I've seen recommendations for both .91 T4 and .80 gated T3. So what would be the best exhaust housing, since this is a street truck?
